Laser furnace for growing large single crystals

In cooperation with the RIKEN Center for Emergent Matter Science and Mr. Yoshio Kaneko, Quantum Design Japan have developed two laser furnaces (1 kW and 2 kW) to produce single crystals. Both types work with 5 lasers which guarantee a uniform power density in the furnace area. The laser profile has been optimized to reduce thermal stress during the growth process. In addition, the system comprises an integrated temperature sensor for real time temperature monitoring. The system reaches 3000 °C, so even materials with a very high vapor pressure can be melted and single crystals can be produced which:

melt within a very small temperature range

have a high vapor pressure near the melting point

have a high thermal conductivity coefficient like metallic compositions
